I've got 3.
Ruth- Strong singer, great personality, versatile, puts lots of emotion into her performances, noone tries harder than her in the competition and noone wants to be there any more than her. And she err ... wears the best dresses
Alexandra- Arguably the best technical singer X Factor has ever had, good personality and she really tries
JLS- The first group on X Factor I've found it worthwhile to support, come out week after week with good performances and they just seem like normal lads
